China's Mining Machinery Developing to a Powerful Country

(1) The digitization of the company's collaboration enables the resources of the remote and different companies to be shared, and the network technology represented by the Internet enables the information and knowledge in all aspects of design and manufacturing to be circulated and integrated on the basis of the digital description. Grouping, distribution, and flattening become possible, providing conditions for users to intervene in production, supply chain, and manufacturing companies to ensure product availability and quality.

The future mining machinery manufacturing system is no longer a steady-state combination of a single enterprise and a limited supplier of long-term cooperation, but an optimal dynamic system without borders, multi-enterprise, and short-term. Large-scale mining machinery and equipment has the characteristics of high technical content, large investment volume, small batch size, poor working environment, and long development and test period. Its development is suitable for adopting a global distributed networked collaboration model, which can quickly respond to market demands and realize the world's most resources. Optimal configuration, through the virtual value chain, quickly meet the fundamental needs of maximizing customer value.

(II) Development of mining machinery products The basic idea of ​​digitalized product development is to use the figures to quantitatively express, store, manage and control various information in the product development process, including graphics, data, knowledge and skills. Rapid market response and innovative development aim at global optimization operations. At present, the development of mining machinery products such as excavators and loaders presents trends of digitization, parallelization, integration, and knowledge. The number has become the core technology for rapid innovation and development. An important feature of digitizing product development is the predictability of product development and product performance. The purpose of the digital simulation of the manufacturing process is to reveal the nature of the manufacturing process, obtain knowledge, and independently design the manufacturing process equipment to achieve product manufacturing and assembly by means of calculation models and computer previews based on physics and mathematics. And even the entire life cycle of the product's forecasting and optimization control capabilities.

The main contents include:

1) Simulation of design process, including shape simulation, assembly simulation, kinematics simulation, dynamics simulation and multidisciplinary integrated simulation;

2) Process simulation, including cutting process simulation, welding process simulation, stamping process simulation and casting process simulation;

3) Production process simulation, through the establishment of a static model and a dynamic model of the manufacturing system, to accurately predict the technical feasibility, processing costs, process quality and production cycle.

(III) Green design of mining machinery Faced with increasingly severe constraints on resources and the environment, mining machinery is a major resource-consuming resource and the source of pollution. The design and management of the product's full life cycle, which is closely related to 4R, is an important means to reduce energy consumption and pollution and achieve sustainable development strategies.

The specific measures are:

(1) Adopt the design principle of long life, low energy consumption and weight reduction. Extending the product life can reduce the mechanical production and reduce the amount of scrap. Reducing the energy consumption of products can reduce the pollution to the environment; while lighter weight and higher efficiency can reduce the consumption of materials and resources.

(2) Minimize the pollution caused by the disposal of waste parts and components and optimize the overall cost. The mining machinery products should be considered in the initial stage of design, with simple handling, low cost, and low pollution. The parts and components must be disassembled conveniently and broken easily. Can be incinerated or can be used as a fuel recovery problem. Use low environmental load materials as much as possible, and do not use harmful materials such as Freon (air conditioner), chlorine rubber, resin and asbestos as much as possible.

(3) In particular, the design of structural parts should use large modular structures and non-toxic materials that are relatively easy to assemble and disassemble, use renewable materials and resources, and increase the regeneration rate of mechanical materials;

(4) Reduce pollution to the surrounding environment and reduce overall machine vibration and noise.
